INVEN'TH To all whom t may conce-rn Be it known that I, FRED A. MAYnns, a cit-izen of the United States, and a resident of Petersburg, in the county of Monroe and State of Michigan, haye invented a certain new and useful Kerosene-Vaporizer; and I do hereby declare the-following to be' a full, clear, and exact description of the invention, such as Will enable others skilled in the art to Which it appertains to' make and use the same, reference being ha to the accome panying drawings, and to th!` characters of reference marked thereon, which form a part of this specification.

This invention relates tolli/luid fuel vaporizing means, and particu arly to means of this class adapted for use in vaporizing kerosene preparatory to burning in internal combustion engines. u

The primary object of my invention is the provision of an improved vaporizing means of the class described, which is adapted to he used in connection With thev customary earbureter and is operable to eii'ect a thorough and eiiieientheating, breaking up and vaporizing of kerosene or similar hydrocarbon oils .into a highly combustible gas eilicient for use in internal'combustion engines.

vThe invention is fully described in the following specification, and While, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the-accompanying drawings, in Which- Figure 1 is a central longitudinal section of a 'vaporizer embodying the invention.

Figs. 2 and 3 are cross-sections taken respectively on the lines 2-2 and 3 3 in Fig.

1. Fig. 4 is a cross-setion of the easing of the vaporizer taken on the line 4 4 in Fig. 1, with the core member and front plate removed, and Fig. 5 is a longitudinal section taken through the front plate on the line 5-5 in Fig. 3. y

Referring to the drawings, 1 designates a casing, which has one side open, as shown in Fig. 4, and is provided in one end-With an exhaust outlet 2. ,A core member. 3 forming ka circuitous tube or passage for the fuel to he vaporized, is `inserted into they easing 1 through the open side thereof, and seats atits rear or inner a ange e, which extends around the rear interior portiA of the casing 1 andfcoperates therewith nd with the core member to form a .rear e einher-5 into which the hot Specification of Letters Patent.'

exhaust gases from the associated engine are first introduced. The front casing l is'closed by a plate 6, which cooperates with the easing and core member to form a front exhaust chamber 7, which has communication with the exhaust outlet 2.

The core 3 primarily comprises a oireuitous tube or conduit having the entrance portion 8 at the central bottom part of the core and then dividing and extending' in opposite directions around the interior of the casing l longitudinally thereof to form the parts 9, 9, with the ends of such divided parts meeting at the central top portion of the core and then extending down interiorly of the core at 10 and forming the oppositely extending parts or ll, 1l., which :'rorm a mixing chamber and are disposed longitudinally of the core and have the outlets l2, 12 at their ends. Thesev outlets extend through the rear side of the easing and are arranged to connect with the customary intake manifold openings V`oi" an engine, two of 'which openings are usually provided in four cylinder engines. t

A steam. chamber 13 is provided in the core immediately below and centrally of the miX- i ing chamber, and communicates with the inthrough openo a cavity or cup portion 15 disposed centrally in 'thebottom Wall of the mixing chamber. jacent portions of the core tube are connected by a web 16, which is provided with a plurality of openings 17 through which the exhaust gases pass from one to the other of the ohambers and 7. The bottom ofthe easing 1 is provided with an opening, which extends inward from the outer side edge thereof and is adapted to have the stem por? tion 8 of the 'core tube project downward therethrough when the core is disposed Within the casing. The part 8 artially fills 'the casing opening' in which isposed and has a flange or lip 18 projecting from its outer open side of the The ad- .will

side to fill the remainder of said opening, as Y Water is supplied to the steam ehamben the casingtop and into the central top por-- tion ofthe core member 3 in register with the passage 10 therein and over the cup 15.

A plurality of-tubes 2l are disposed'transversely through the core member in position to pass through the mixing chamber 11 below the entrance 10 thereto and over the cup 15 so that the fuel in its passage through the core tube is required to pass around the tubes 21 in entering the said` chamber from the passages 9, 9. 4The tubes 21 openr eomlmunication between the exhaust chambers 5 and 7 yso that they become highly `heated by the'passage of the exhaust gases therethrough, thus effecting a thorough breaking.

up and vaporizing of the liquid fuel coming in contact therewith. An exhaust passage 22 is also provided through the core meml ber immediately below the steam chamber 13 andfopens communication between the exhaust chambers 'and 7. i

The exhaust chamber 7 is provided with a space entirely around the core member 3 inadvanee ofthe flange 4f so that the. entire surface of the core member is exposed to the exhaust gases. 'lhe exhaust passage vfrom within the casing 1 Vare re quired to pass through an opening 23 provided in the bottom of the chamber 7 around the core part 8 and thence to the outlet 2 through a passage 24, which is provided longitudinallyin the ease l'below the bottom of the chamber 7 L The rear irelosed side of the casing 1 is provided with oneor more openings 25 ,through which the exl gases' may be'v introduced to the chamber The plate 6 may be, and in the present instance, shown having a' backwardly and forwardly extending passage 26, which is formed within said cover and has" an inlet opening 27'at one end and an outlet opening 28 at its other end. rl`he inlet open-v ing 27 has communication with the atmosphere whereby cool air enters the passage 2li through said opening, while the outlet open-l ing 2H has eomiiiunicatioii through :i pipe 29 with the air inlet of the associated rarbureter, not shown. It is thus evident that the air in its passage through the plate 6 will become highly heated by reason of the pas-` `vbetween the carbureter and engine in the place of the` customary intake manifold so that the fuel mixture after leaving the car. bureter is required to through the circiiitous passage 8, 9, 10, l1 of the core member 3 and to be thoroughly:vaporized` and converted into a highly combustible gas by. the heat to which it is subjected when traversing Said passage, such beat being occaf liquid to start theL motorwhen-co gases in their' sioned by the passage of the exhaust gases through the easing l and through and `around the core member 3. The heated tubes 2l with 'which the fuel comes in direct 4contact facilitate the breaking up and vapori' 70 nation thereof. The steam which is gener-f" ated froingvwater within .the steanireli'ambei '13 passes through the ports 14 into the mixi jing chamber formed by the passage armsS l1, vl1 and mixes with the vaporized fuel. 75 ylt is --found thatthe mixing of a small amount of moisture with the fuel prevents to avery large extent carbon forming in A:the `motor cylinders. In Vstarting a. motor equipped with n 1y 'vaporizer of gasolene or other suitabhA priming liquid v of a highly combustible nature is introduced into the cup or cavity 15 in Ithe bottom of the' mixing chamber vl1 from the priming cup 20. i The/cup 15 is adaptedto-hold su starting requiring about 'thirty seconds 'to heat the vaporizer sufficiently to make a change to kerosene as theloperatin fuel It is evident that .should either t 1e casing 90 or the core member'of my vaporizer be broken, thereby necessitating repair or ro?. placement, one may easily and quickly loeremoved from the other for such purpose b v first removing the plate 6 and d iseonnectings the priming and water supply tubes `from [the core member.

I wish it understood that my invention is. not limited to any specific constructiomara small quantity rangement or form of theparts, as it-is` capable of i'iuinerous modifications without departing from the spirit of'f'the claims. ,v
